- the invention relates to a pneumatic vehicle tire having a tread with circumferential grooves and at least one circumferentially circumferential rib profile, in which grooves are formed, which open at one of the groove flanks of the profile rib laterally bounding circumferential groove in this, wherein the groove flanks of the circumferential groove below
- Broadening of the circumferential groove towards the tread periphery extend at an angle of 12 ° to 17 ° to the radial direction.
- a pneumatic vehicle tire having such a tread is known from EP 2 239 153 A1.
- the tread has a number of tread ribs separated by circumferential grooves.
- On the shoulder side profile ribs are provided which are traversed by transverse grooves, which open with a short, a reduced depth portion in the tread the inside of the tread rib limiting circumferential groove to the

- a similarly designed tread has the vehicle pneumatic tires known from EP 3 037 282 A1.
- Tread periphery are widened by a chamfer, which respectively at the
- the inside of the channel on the inside of the trough ensures a quiet rolling noise and helps drain water into the circumferential groove on wet surfaces.
- tread ribs depending on the position in the tread, have a higher rigidity than other tread ribs. This applies, for example, to the shoulder-side profile ribs, which should have a relatively high rigidity, in order to ensure a good lateral force build-up.
- the negative portion in this tread rib is kept low. The small negative portion is disadvantageous for the water drainage in the transverse direction of the tread.
- profile ribs therefore have to ensure the drainage mostly narrow grooves or cuts, which are oriented in the transverse direction, whereby, however, the rigidity of the tread ribs is reduced and also develop deficiencies in the rolling noise in the 1000 Hz range.
- the depth and the width of the cuts or narrow grooves play a certain role. It is common that in profile ribs a compromise in the design with
- Sections and / or narrow grooves is taken so that either the stiffness and the rolling noise or drainage are at the desired level.
- the invention has for its object to improve a pneumatic vehicle tire of the type mentioned so that the mentioned conflict of objectives between stiffness and noise reduction on the one hand and the drainage capacity on the other hand is much better solved than before.

- Tread periphery extending bottom, which is located in a radially determined distance of 0.5 mm to 2.0 mm from the lowest point of the groove bottom of the circumferential groove.
- the shallow depth of the grooves is particularly favorable for a high rigidity of the tread rib.
- the discharge path becomes the circumferential groove shortened, whereby an improved and accelerated water drainage from the grooves can be found in the circumferential groove.
- the round design of the recesses avoids the emergence of unfavorable water vortex.
- the small depth of the grooves and their relatively large inclination to the axial direction provides a largely "closed" tread rib, whereby the noise emission of the tire is reduced to the outside in the 1,000 Hz range.
- Indentations and their bottom, in plan view of the tread a D-like shape on. Particularly favorable is also an embodiment in which the indentation and its bottom in plan view of the tread have a circular segment-like shape, wherein the circular segment is at most a semicircle.
- the concavely rounded boundary wall of the recess extending between the bottom and the tread periphery is inclined to the radial direction at an angle of 2 ° to 5 °. This inclination gives the indentation a total of a funnel-like shape, which also supports the discharge of water from the grooves in the circumferential groove.
- junction areas of the grooves are preferably located on the furthest groove flanks on the inside regions of the indentations, so that the aforementioned advantageous effects of the indentations on the water drainage can fully come into their own.
- the most inwardly located point of the indentations on the tread periphery at the level of the other peripheral edge of the groove flank of the circumferential groove or against the position of the other peripheral edge of the groove flank is up to 2 mm within the tread rib.
- Particularly balanced properties in terms of stiffness, noise reduction and water drainage capacity of the grooves are supported by preferred embodiments of the grooves.
- the grooves have a U-shaped or a V-shaped cross section, further, if the grooves have a depth of at least 1.5 mm and at the tread periphery a maximum width of 2.0 mm to 5 , 0 mm own.
- Particularly preferred in this context is an embodiment in which the grooves have a width and a depth which, starting at their ends in the tread rib, become continuously larger in the direction of their mouth regions in the indentations.
- an incision in each case adjoins the end of the grooves located in the profiled rib.
- Such incisions may, for example, open into a circumferential groove which bounds the tread rib on its second side or, if the tread rib is a tread rib extending on the shoulder side, over the ground contact surface of the tread rib
- profile ribs which are shoulder-side profile ribs, since such ribs should have a particularly high rigidity to ensure good lateral force buildup when cornering.
- 1 is a plan view of a peripheral portion in the shoulder-side region of a tread of a pneumatic vehicle tire
- Fig. 2 is a sectional view taken along the line II-II of Fig. 1 and

- the grooves 4 extend relative to the axial direction at an angle a, which is 45 ° +/- 20 °, and have a slope relative to the axial direction, which coincides with that of the transverse grooves 3.
- the grooves 4 are substantially parallel to each other, which means that within a FaufstMails the angle a can deviate from each other by up to 10 °.
- each groove 4 has a depth which, starting at its closed end in the direction of the junction area in the circumferential groove 2 is continuously larger, the groove 4 at its end in the tread rib 1 a depth ti of at least 1.5 mm and at their junction in the Circumferential groove 2 has a depth t 2 , the highest is 3.5 mm and in particular by 10% to 20% greater than the depth ti.
- the cross-section of the groove 4 is V-shaped or U-shaped, its width b 2 increases, starting at its end in the tread rib 1 in the direction of the junction area in the circumferential groove 2 and 2.5 mm to 5.0 mm at the junction ,
- the grooves 4 open at local indentations 7 of a groove flank 5 in the
- Each indentation 7 has in plan view of the tread a D-like shape, with a top view in D-like bottom 7a and along the groove flank 5 extending, rounded overall boundary wall 7b, which, as shown in FIG. 3, at an angle g is tilted from 2 ° to 5 ° to the radial direction, so that the indentation 7 widens somewhat in the direction of the tread periphery.
